 Introduction: The True Cost of Aluminium Decking Beyond Initial Price

With global aluminum prices projected to rise 15-20% by 2026 and supply shortages looming, understanding the real cost of aluminium decking has become more critical than ever for homeowners and developers alike . While initial price tags often grab attention, smart investors know that long-term value depends on a complex calculation of material costs, installation expenses, maintenance requirements, and durability factors. In this comprehensive guide, we'll break down every component that contributes to aluminium decking costs, compare it with traditional materials, and show why Shimei's aluminium decking delivers unmatched cost efficiency over its 60-year lifespan.

 

Breaking Down Aluminium Decking Costs: What You're Actually Paying For

1. Material Costs: Quality vs. Affordability

The average material cost for aluminium decking ranges from $15 to $20 per square foot, but this can vary significantly based on alloy quality . Shimei's use of aerospace-grade aluminium alloy—typically 20% more expensive than standard commercial alloys—directly translates to 30% greater corrosion resistance and 50% longer lifespan. This premium material explains part of the cost difference but delivers exponential value over time.

 

In contrast, lower-grade aluminium ($10-$12/sq ft) often contains higher impurity levels, leading to premature oxidation and structural weakness in harsh weather conditions—a false economy that results in earlier replacement costs.

 

2. Installation Expenses: Efficiency Matters

Professional installation adds $15 to $25 per square foot to your total aluminium decking cost, but Shimei's innovative click-lock system reduces labor time by up to 40% compared to traditional screw-down methods . This efficiency helped a recent residential project in Sydney complete a 100 sq ft deck in just 2 days instead of the projected 3-4 days, saving approximately $800 in labor costs.

 

3. Long-Term Maintenance Savings

While wood decking requires $3-$5 per square foot annually for sealing, staining, and repairs, Shimei's aluminium decking needs only occasional cleaning with mild detergent . Over a 10-year period, this translates to savings of $30-$50 per square foot—more than offsetting the initial cost difference between aluminium and wood.
